Nikita Popov b3d99ac2cd [CodeGen] Use data layout aware constant folder in CGBuilder (#184819)
Use the DataLayout-aware TargetFolder instead of ConstantFolder in
Clang's CGBuilder. The primary impact of this change is that GEP
constant expressions are now emitted in canonical `getelementptr i8`
form. This is in preparation for the migration to ptradd, which requires
this form.

Part of the test updates were performed by Claude Code and reviewed by
me.
